There are three main modules for the class. The first part is how to look at the sky above us. This encompasses how scientists figured out how large the Earth was, how we know the Earth goes around the sun, why we think the universe started with a “big bang”. The second module is explaining life around us. This part focuses on evolution, including how the idea was originally derived and what evidence supports it today. The last is how to look at the Earth below us. We will focus on two aspects: How do we know how old the Earth is; and, What wiped out the dinosaurs?
